Nice work! Does it feel like a substantial upgrade or more just a functional replacement?
I've not used it myself yet aside from testing that it works, but I will want to shower tomorrow so we will see. I believe it has a stronger flow (which makes sense as the older one had a pump that was starting to fail), so you have to reduce it further to get the water to be hot enough, even with the slightly higher kW rating. We don't lose anything there though, it will vary during hotter or colder seasons anyway, and I'm sure we had to reduce the flow further on the old one did when it used to work properly too. Failing motor = higher flow setting to achieve the same flow, I guess. It really sounded like it was going to die within a week or two so yeah, we just binned the old one.
